To all whom t may concern:

Be it known that I, FRANCIS JOSEPH CoL- LIN, a subject of the Kingof Prussia, and residing at Dortmund, Kingdom of Prussia, German' Empire, have invented certain new and useful Improvements in Coke-Ovens, of which the following is a specification.

The present invention relates to that type of coke ovens which is generally designated as horizontal ovens and is particularly directed to that part of such structures which controls the supplying of combustion gases to the individual nozzles in the walls between the coke chambers.

`In the drawings there are illustrated three variations of structure.

Figure 1 is a longitudinal section through one of the heating Walls, and Fig. 2 represents a transverse section on the line affof Fig. 1. Figs. 3 and 4, and 5 and 6 respectively are similar views of two alternative forms, Fig. 4 being a section on line c-cl of Fig. 3, and'Fig. 6 a section on line c-f of Fig. 5. Fig. 7 is an enlarged detail of a portion of the oven'shown diagrammatically in Fig. 1. Fig. 8 is a transverse section on the line g-h of Fig. 7 and Fig. 9 is a transverse section on the line vI-c of Fig. 7. 4

According to the present .invention the combustion gases are supplied to the nozzle not directly from the source of supply but from a moreor less centrally located reservoir or chamber which `being enlarged as compared with the transverse sectional dimensions of the gas supply (cf. 1 of Figs. 1, 3 and 5 with 1a of Figs. 2, 4 and 6) acts as a temporary storage chamber from Awhich each of the nozzles draws its supply. As shown in the drawings the duct which supplies the incoming gases, the storage chamber for these gases andthe ducts leading from said chamber to the nozzles are all built into the masonry of the oven in that part thereof which is located beneath the flues. The main object of these constructions is to prevent the gases from becoming overheated. In order to bring about this result the full quantity of the gas is first passed undivided to the center of the oven where due to the enlargement of the chamber'thc movement of the gas is retarded before they are distributed to the individual nozzles.

In addition to the supplying ofthe gas in such a way as to prevent its overheating and consequent decomposition, the construction, as will readily be seen, is such that the gas that feeds the nozzles nearer the coolest ends of the oven is subjected to the greatest heat so that the degree of preheating is adjusted throughout the oven to the relative temperature of the oven at any point. The entire gas supply system as shown in the drawings, is loc-ated in that part of the walls which is subjected to the least amount of radiated heat c; below the nozzles and heating fines-an arrangement which, when employed, brings about more satisfactory results than if the gas supply system were incorporated in a hotter part of the structure.

In the drawings the centrally located chamber is designated with numeral 1. In Figs. 1 and 2 the gases are introduced into the wall of the .oven through the channel 1a from which they enter the enlarged chamber 1 which is located near the center of the wall. This arrangement is duplicated at the other side of the wall so that there are two of such chambers 1 near the center of the wall. From the chamber 1 the gases distribute themselves to the individually gaged or calibrated nozzles. 2 through which they enter the individual iiues 3 in which they meet the air used for combustion which enters through the inclined slits 5 which communicate with the common air supply flue 6. The coking chambers are designated by the numeral 7. The products of combustion pass from the lues 3 into the small iues 7 (see Figs. 7 and 9) and pass downwar ly therethrough into the sole flues S of tie adjoining oven (see Figs. 8 and 9). These sole lues 8 alternate with the air supply iues 6 and discharge the incandescent vcombustion products, if desired, into suitably constructed and arranged regenerators (not shown). During one phase of the operation a particular regenerator is being heated in this manner while during the next phase the heated regeneratoil is connected with the air supply for preheating the air before its passage through the lues 6 and slits 5 into the combustion i'lues 3. In Figs. 3 and 4 the combustion gases instead of being withmon flue which communicates, with each of the nozzles 2- (as shown in Fig. l) are supe plied to groups of nozzles by separate and independent passages and chambers but herel again the gases are lirst permitted to accumulate in a common reservoir or chamber 1 before any of the nozzlescan be supplied. Figs'. 5 and 6 illustrate an oven built just likethe one shown in Figs. l and Q except that the two chambers 1-1 of Fig. l are mergedvinto a single chamber. In that case the entering luelel through which the gases are conducted tonthe chamber l need be located only`on ne side of the oven in stea -oi at both as would be the case if the structure of Fig. 1 is employed.

v hen gases are distributed 'according to the method thus described, there will always be near the center of the oven a relatively large accumulated supply of gas sufficient to supply in adequatemeasure'the'requirel ments of the various'burner' nozzles. The heat in the oven the separation of a certain amount of hydrocarbons out of the combustion gases, ,but where a central reservoir or chamber is used,

such effects are negligible by reason of the f capacity of the chamber l t'o act as a storage chamber for an enlarged or accumulated common source of such decomposition or separation Iof heavy hydrocarbons is thus very much diminished if not entirely obviated and the gases being maintained in large volume in the center of the' oven are not exposed to the likelihood of becoming overheated. I y i The essence, therefore, of the present invention resides in the fact that 4the full .In this way the quantity of gas is first brought in an un# divided condition to about the middle of each wall where it accumulates in a com-v mon chamber, preferably enlarged, from which chamber it is lirst divided and distributed to the individual nozzles. Moreover, a pre-'heatin of the gas is effected in the tlues leading irom the central chamber to the nozzles whereby the gas conducted to the nozzles near the oven ends,'whichare the coolest parts of the oven, travels the longest distance and is therefore most strongly pre-heated while that conducted to theV has a tendency t0 `cause 4.burner nozzles with gas `chamber,`the said two supply.
